JAMES A. CAMERON, 0F BROOKLYN, AND JOHN A. HAWKES. OF NEW YORK, N. Y.,

ASSIGNOBS TO CAMERON MACHINE COMPANY, OF BROOKLYN, NEW YORK, A COR-POBATIOH OF NEW YORK.

BLITTING AND RE'WINDING MACHINE.

To all whom it may concern:

Be it known that we, James A. CAMERON and Joan A. Hawxrs, citizens ofthe United States, and residents, respectively, of the borough of Brookln, county of and State of New ork, and of the borough of Bronx, countyof Bronx, city and State of New York, have invented certain new anduseful Improvements in Slitting and Rewinding Machines, of whichthefollowing is a specification.

The present invention relates to slitting and rewinding machines, andmore articularlyto machines espmially adapte to the slitting and rewindmof paper of tough fiber or of-tacky or a esive material, or of tin foil.

Whencutting tacky or adhesive material or the like it sometimes happensthat the edges of the slitted sections will re-adhere after beingseparated, thereby rendering it difficult to separate the rewound coils.ifficulty is also experienced in separating coils of rewound materialwhen the diameter of the coils is exceedingly large and the width of theslitted sections is exceedingly narrow.

. The main object of this invention is to insure the permanentseparation of materials of this character after slitting and during therewinding.

In carrying out this and other objects, the invention consists of thehereinafter claimed features of construction,. combination of arts andarrangement of elements, a preerred form of which is disclosed in theac-' companying spechication and drawings.

In the said drawings: Fi re 1 is a longitudinal vertical sec tiona viewtbrou h a machine embodying a.

preferred form 0 the invention.

Fig. 1 is a detail view of one of the slip drive connections interposedin the line of gearing.

Fig. 2 is a fragmentary plan view of the spreading means located ajacent to the rewindin device.

Fig. is a sectional view showing one of the tension and separatingrollers projecting between the coils of the rewound material.

Fig. 4 is a transverse sectional view on the line 4-4 of Fig. 2.

5 constitute the slitting means and, as shown, 0

are preferably of the score cut type, the backing roller being glasshardened and harder than the cutter 5.

The slitted sections of the web 2 may now pass directly over the backingroller 4 to 66 the hi roller 6, or thei may pass around the guide roller7 and t ence back between the backing roller 4 and nip roller 6. If thematerial takes the latter course separating blades 8 may be employedwhich project in between the slitted sections of the material and severany unsevercd threads or fibers.

The nip ro]ler 6 en ages with the upper side of the backin ro ler 4 andis mounted in the arms 9 (on y one of which is seen),

said arms being pivoted on the shaft 10. The latter, in this instance isprovided with a gear 11 which convenient] receives its motion from thegear 12-on the shaft 13 of the backing roller-.4. Mounted loose from theshaft 10 is another gear 14 between which and the car 11 there is a slipfriction drive 15, the s ippnge of which is adjusted by means of thespring 16 and nut 17. The

gear 14 meshes with an intermediate gear 18 B5 .on one ofl the arms 9which in turn is in mesh with the pinion 19on the nip roller 6. Byadjusting the tension of the spring 16 the amount of slippage can be ad'usted and consequently. the tension of the n1 roller 6 on the slittedsections can be vari The slitted sections of the web 2 now pass over thetable 20 and in between the pins21 which constitute a comb extendingtransverscly of the table for separating the slitted sections.

22 is a tension roller extendin transverselyof the machine and provi edwith separating blades 23 between which the web sections pass, afterwhich they are led underneath the bat-kin roller 24 of the rewindingdevice, an thence over tension roller 25 also provided with separatingblades, and thence to the reivinding shaft 26. The rewinding shaft 26 ismounted in the arms 27 (only one of which is seen), which arms arepivoted on the shaft 28. lly reason of this construction the rewindingshaft 26 will become displaced with respect to the backing roller M asthe diameter of the reu'ound coils increase. Motion is im parted to therewinding shaft by means similar to those which transmit motion to thenip roller 6. That is to say: there is a gear 29 on-the shaft 30 of thebacking roller 24 which meshes with a gear ill on the shaft 28. Looselymounted on this shaft 8 is another gear 32 between which and t e gear 31there is a slip friction device similar to 15. The gear 32 meshes withthe intermediate gear 35 on one of the arms 27, which .in turn drivesthe pinion 36 on the rewinding shaft 26. A counterweight 37 isadjustably mounted on the extension 38 of the arm 27 and may be used tocounterbalance the weight of the rewound material.

From the foregoing construction it follows that; by adjusting thetension of the slip friction devices the material may he ledunderconsiderable tension over the hacking roller 4: to prevent wrinkling andmay be loosely rewound if. desired, or vice vcrsa,

, or the web sections may be fed from the nip roller 6 to the separatingand rewinding devices without ovcrpulling by the latter. The provisionof a slip friction drive for the nipping roll 6 is chiefl important inthat the nipping roller may e driven at a differ- .ent peripheral speedthan that of the backwill be obvious.

ing roller 4 to thereby produce relative motion between the two rollers.This results in causing 'the nipping roller to exert a rubbing orsmoothing action on the web, as

In fact by the various independent adjustments descrihed the machine maybe suited to work on different materials.

Motion may be imparted to the two ends of the machine by means of theshaft 38 provided with bevel gears 39 which mesh wi h correspondingbevel gears on. the shafts 30 and 1 3.

In Fig; 1 the tension roller 25 is shown as projecting into the coils ofrewonnd material, thus keeping the web sections Separated whenrewinding. This tension roller 25 is here shown as being pro idedaiiit ha counterweight-4O which servcs tokcep it, in engagement; with theren'ound coils.

Fig. 5 the construction is substantially the same except that a chain 41is utilized to connect the shafts 30 and 13. Also in this instancerollers 42 and 45 are arranged at either end of the table 20. the roller15 having separating blades 46. and a tension roller 1-; counterweight dat It and prnvidml with separating blades 18 extends n between the coilsof rewound material. The web sections here pass directly from the table20 over the roller 45 and thence over the tension roller 43 to therewinding shaft .26 lalwvmt the latter and the hacking member 24.
